Development Status

Alpha. ProbOS implements one governed Cognitive Mesh with an experimental federation transport. The getting-started path is Beta: an automated test runs the Quickstart from probos setup on.

Snapshot (October 2026)

Measured on main on 2026-10-07. The agent figures come from booting the shipped config/system.yaml with the built-in mock LLM client; a smaller configuration, such as the one probos setup writes, boots fewer agents.

Metric	Value
Python tests (pytest --collect-only)	39,707
Vitest test files	357 (HXI) + 10 (desktop host)
Python modules in src/probos	993 (~344,000 lines)
Agents at boot	81, in 51 pools
Sovereign crew agents	15, in 6 departments
Pool groups	9 (Bridge, Core Systems, Engineering, Medical, Operations, Science, Security, Self-Modification, Utility)
Shell slash commands	61
API router modules	67
Sections in config/system.yaml	181
Architecture decisions	AD numbers past AD-1300
Latest tag	v0.4.0-phase29c (March 2026); no release since — PyPI packaging is tracked in #1053

Eras

Era	Highlights
I — Genesis (Phases 1–9)	Substrate, mesh, consensus, cognitive core, shell, federation transport
II — Emergence (Phases 10–21)	Self-modification, skills, LLM tiers, dreaming, persistent knowledge, Shapley trust
III — Product (Phases 22–29)	HXI, Discord adapter, bundled agents, medical and science teams
IV — Evolution (Phase 30+)	Standing orders, Ward Room, sovereign DID identity, ontology, Cognitive JIT, self-regulation, emergence metrics
V — Unification	Knowledge graph, brain-enhancement work, commercial-overlay seam
VI — Commercial Bridge (May 2026)	Extension-point registry, NATS cognitive-chain pipeline, contagion firewall, voice substrate

Since June 2026 the work has been organized as programs rather than eras:

Program	What landed
Agentic execution and tools	A multi-turn agentic loop with tool search and delegation; MCP servers with per-agent and per-tool authorization; governed Python execution in per-agent workspaces; office-document agents; a browser tool and browser workstation
Crew execution and approvals	Durable crew sessions with recovery and verified finalization; work items agents can discover and claim; an approvals center; delegated approvals with chain-of-command routing and decision pre-clearance
Composable cognition	The cognitive spine and organ contracts, with attention and dreaming as the first organs (design)
Onboarding	probos setup provider wizard, probos doctor, and a tested Quickstart
Identity and federation	Ed25519 key binding for the ship's did:probos identity, signed federation envelopes, and authenticated peer admission proven between two separately started nodes (AD-1196–1198)
Platform maturity	The AD-1270 program: exercised capabilities, robust seams, modular owners, fast gates and truthful docs

Current Priorities

From the Roadmap (2026-09-07):

1. Finish the dependable mesh — AD-1270 / #1324.
2. Measure benefit as paths become ready — the Sigma ablation (#1064) and Ship Trials (#1123).
3. Bring human contribution and independent adoption forward — typed human claims (#1136) and a PyPI release (#1053).
4. Authenticate before wider federation — fleet policy (#479) follows the two-node authentication now in place.
5. Keep extensions tied to outcomes — elastic-team trials (#1337) and governed self-maintenance (#1352).

Nooplex Readiness

From the Nooplex Readiness Map, which is the authority for these claims:

Tier	Name	Status	Permitted claim
A	Dependable Cognitive Mesh	planned	"ProbOS is an alpha implementation of a governed Cognitive Mesh."
B	Secure Multi-Mesh	planned	"ProbOS has an experimental federation transport."
C	Nooplex Core Fabric	not-started	"ProbOS provides local foundations for a future Nooplex Core."
D	Emergence Research	research	"ProbOS is an experimental platform for testing the Nooplex hypothesis."

Live GitHub issues and their evidence receipts are the completion authority; PROGRESS.md and DECISIONS.md hold the narrative and decision logs.
